It's been surprisingly easy to avoid. Facebook doesn't know me, so random strangers uploading a photo with me in the background can never associate it with my identity. And people who know me don't post my photo. The concern is not so much with people finding me, it's with the unknown data processing they could be performing. I just wonder if those random photos where I make an appearance without being tagged are getting cataloged and a profile for this 'unknown individual' is being built so that it can be linked with my identity if there is a slip someday. I don't quite have the nerve to ask relatives for photographs of people who died in the 20th century to put up as my own photo to confuse their sensors, though, so I suppose it will eventually be unavoidable to be correctly cataloged and tracked.
